7.2.1 Lubrication
A bearing (motor side)
The A bearing (motor side) has life long lubrication
and is therefore maintenance free. After 20,000 op-
erating hours or 2½ years (3- shift operation), the A
bearing must be replaced by a qualifi ed professional
or by our authorised workshops.
B bearing (side facing away from the motor)
The B bearing (on the side facing away from the mo-
tor) must be lubricated on the grease nipple (Fig. 4/
L) with 4g of grease after 3,000 operating hours but
no later than after one year. To lubricate the inlet
grating (Fig. 4/G) must be unscrewed.
NOTICE
Do not overfi ll the grease reservoir (Fig. 5/c) on
the B bearing.
We recommend the following brands of grease:
KlüberPetamoGY193 or other equivalent greases
(see also grease recommendation plate (Fig. 4/M)).
7.2.2 Blades
Blade check:
V-KTR models have 7 carbon blades that gradually
wear out during operation.
First check after 3,000 operating hours and then
every 1,000 operationg hours or, depending on the
height (Fig. 5/X) earlier.
Remove inlet grating (Fig. 4/G) as well as screws
(Fig. 5/s). To lift the housing lid (Fig. 5/b) from the
housing two screws (Fig. 5/s) must be screwed into
the two tapped holes (Fig. 4/a) on the housing lid
evenly. Remove the blades (Fig. 5/d) to be checked.
All blades on the machine must have a minimum
height (Fig. 6/X) of more than 26 mm (V-KTR 100)
and 32 mm (V-KTR 140) and a minimum thickness
(Fig. 6/W) of more than 2.5 mm.
The blades must only be changed as a set.
